LOUIS ARONOVITZ, OF NEW YORK, N. Y.

CONSTRUCTION OF CEILINGS.

SPECIFICATION forming part of Letters Patent No. 600,704, dated March 15, 1898.

Application filed August 27, 1.897. Serial No. 649,704. `(No model.)

To all whom, it Iii/my concern.-

Be it known that I, LOUIS ARoNowrrZ, of New York city, in the county and State of New York, have invented a new and useful Improvement in the Construction of Ceilings, of which the following is a full, clear, and exact description.

My invention relates to an improvement in the construction of ceilings; and it consists in a panel formed of bars and connectinglinks in such a manner that it may be folded for transportation and inserted between the lianges of the ordinary floor-beams, being at the same time expanded into its normal shape.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the Views.

Figure l is a plan view of a section or panel, showing my improved construction. Fig. 2 is a plan view of a section or panel folded. Figs. 3, 4, and 5 are end elevationsof a portion of such panel, showing slightly different constructions.

The object of my invention is to construct the panels immediately supporting the ceiling in such a manner that the bars forming the same may be folded for transportation and expanded when put in place, thus obviating handwork at the building. In constructing these panels the bars B, formed, as shown in Fig. 3, of T-beams, or the bars B', as shown in Fig. 5, of two channel-irons placed back to back, are used to support the material of the ceiling. These bars are connected to each other by short links O, which are pivoted to the flanges of the bars and extend from one bar to the next adjacent bar. The bars are placed at such a distance apart from each other when in their expanded position as to receive a brick or tile placed between them and supported upon the lower flange of the bar. The bricks used for this purpose are shown in dotted lines in the drawings and are indicated by the letter D. The ordinary floor-beams are indicated by the letter A. The cross-bars B, forming the panel, are made of such a length as to fit snugly between the webs of the I-beams A.

In Fig. 2 the bars B are represented as folded l their bottom flanges.

upon each other for transportation. W'h'en put in place in the building, the bars will be inserted between the parallel beams A and expanded into the position shown in Fig. 1. The bricks or tiles are then placed between the vertical webs of the bars and resting upon panel lathing or any other suitable means for holding the plastering may be attached. In using this construction the panels may be quickly put in place and also quickly filled with flreproon g material-such as bricks, tiles, &c.

In Fig. 5 the bars are shown as made of channel-irons placed back to back, thus providing horizontal anges at the top and bottom of the bars. With such a construction the bricks or tiles would be placed between the top and `bottom flanges of the bars, as shown in Fig. 5.

The panels may be put together at a shop in sections of considerable length and then folded so that they may be readily transported. This enables the handwork to be done where especial facilities may be used for assembling the parts, leaving little handwork to be done at the building, which results in a considerable saving in the cost of the construction.

The parts are all securely fastened together, each supportingthe other, and making, consequently, a strong and rigid structure. This construction may also be used in the construction of iioors-fillin g the space between large floor-beams. In such cases it may be desirable at times to place a layer of concrete or similar material over the bricks or tiles. My invention, however, pertains to the construction of the panel, consisting of bars B and connect ing-links C, and the method of using the same with the floor-beams A.

As shown in Figs. l and 3, the links C are placed upon the upper surfaces of the flanges of the bars B. As shown in Fig. 4, these links are pivoted upon the under surfaces of the said flanges. Either position may be adopted.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A ceiling-supporting panel,consisting of a series of bars flanged at their lower edge,

To the bottom of the each ball being connected to the adjacent bars the links and the anges of the langed bars, by pivoted links, substantially as described. substantially as described.
